本文实例为大家分享了kotlin自定义对话框的具体代码供大家参考具体内容如下1.CommonDialog 创建我们自己的对话框,继承于系统的Dialog 实现构造方法classCommonDialog(context:Context?,themeResId:Int):Dialog(context,themeResId){}\2. 在内部创建BUilder类 定义出我们需要的方法和属性classBuilder(privateval context:Context){privatevartitle:String?nullprivatevarmessage:String?nullprivatevarpositiveButtonContent:String?nullprivatevarnegativeButtonContent:String?nullprivatevarpositiveButtonListener:DialogInterface.OnClickListener?nullprivatevarnegativeButtonListener:DialogInterface.OnClickListener?nullprivatevarcontentView:View?nullprivatevarimageid:Int0privatevarcolor:Int0privatevarwithOffSize:Float0.toFloat()privatevarheightOffSize:Float0.toFloat()funsetTitle(title:String):Builder{this.titletitlereturnthis}funsetTitle(title:Int):Builder{this.titlecontext.getText(title)asStringreturnthis}funsetMessage(message:String):Builder{this.messagemessagereturnthis}funsetMessageColor(color:Int):Builder{this.colorcolorreturnthis}funsetImageHeader(Imageid:Int):Builder{this.imageidImageidreturnthis}funsetPositiveButton(text:String,listener:DialogInterface.OnClickListener):Builder{this.positiveButtonContenttextthis.positiveButtonListenerlistenerreturnthis}funsetPositiveButton(textId:Int,listener:DialogInterface.OnClickListener):Builder{this.positiveButtonContentcontext.getText(textId)asStringthis.positiveButtonListenerlistenerreturnthis}funsetNegativeButton(text:String,listener:DialogInterface.OnClickListener):Builder{this.negativeButtonContenttextthis.negativeButtonListenerlistenerreturnthis}funsetNegativeButton(textId:Int,listener:DialogInterface.OnClickListener):Builder{this.negativeButtonContentcontext.getText(textId)asStringthis.negativeButtonListenerlistenerreturnthis}funsetContentView(v:View):Builder{this.contentViewvreturnthis}funsetWith(v:Float):Builder{this.withOffSizevreturnthis}funsetContentView(v:Float):Builder{this.heightOffSizevreturnthis}funcreate():CommonDialog{/** * 利用我们刚才自定义的样式初始化Dialog */val dialogCommonDialog(context,R.style.dialogStyle)/** * 下面就初始化Dialog的布局页面 */val inflatercontext.getSystemService(Context.LAYOUT_INFLATER_SERVICE)asLayoutInflater val dialogLayoutViewinflater.inflate(R.layout.dialog_layout,null)dialog.addContentView(dialogLayoutView,ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT))if(imageid!0){(dialogLayoutView.findViewByIdView(R.id.iv_image_header)asImageView).setImageResource(imageid)}else{(dialogLayoutView.findViewByIdView(R.id.iv_image_header)asImageView).visibilityView.GONE}if(!TextUtils.isEmpty(title)){(dialogLayoutView.findViewByIdView(R.id.tv_dialog_title)asTextView).texttitle}else{// Log.w(context.getClass().toString(), 未设置对话框标题);}if(color!0){val viewByIddialogLayoutView.findViewByIdView(R.id.dialog_content)asTextView viewById.setTextColor(color)}if(!TextUtils.isEmpty(message)){(dialogLayoutView.findViewByIdView(R.id.dialog_content)asTextView).textmessage}elseif(contentView!null){(dialogLayoutView.findViewByIdView(R.id.dialog_llyout_content)asLinearLayout).removeAllViews()(dialogLayoutView.findViewByIdView(R.id.dialog_llyout_content)asLinearLayout).addView(contentView,ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT))}else{(dialogLayoutView.findViewByIdView(R.id.dialog_content)asTextView).visibilityView.INVISIBLE}if(!TextUtils.isEmpty(positiveButtonContent)){(dialogLayoutView.findViewByIdView(R.id.tv_dialog_pos)asTextView).textpositiveButtonContentif(positiveButtonListener!null){(dialog.findViewByIdView(R.id.tv_dialog_pos)asTextView).setOnClickListener{positiveButtonListener!!.onClick(dialog,-1)}}}else{(dialogLayoutView.findViewByIdView(R.id.tv_dialog_pos)asTextView).visibilityView.GONEdialogLayoutView.findViewByIdView(R.id.line).visibilityView.GONE}if(!TextUtils.isEmpty(negativeButtonContent)){(dialogLayoutView.findViewByIdView(R.id.tv_dialog_neg)asTextView).textnegativeButtonContentif(negativeButtonListener!null){(dialogLayoutView.findViewByIdView(R.id.tv_dialog_neg)asTextView).setOnClickListener{negativeButtonListener!!.onClick(dialog,-2)}}}else{(dialogLayoutView.findViewByIdView(R.id.tv_dialog_neg)asTextView).visibilityView.GONE}/** * 将初始化完整的布局添加到dialog中 */dialog.setContentView(dialogLayoutView)/** * 禁止点击Dialog以外的区域时Dialog消失 */dialog.setCanceledOnTouchOutside(false)val windowdialog.window val contextthis.contextasActivity val
